Do/7 VYZwf/M er Patented May 20, 1930 r non v. TANTLINGER, 0F SHERMAN, cALIroimrA BOOMERANG-THROW'ING' DEVIQE Application filed April 3, 1928. Serial No. 266,954.

This invention relates to a device adapted to throw boomerangs or like missiles.

One of the objects'of the invention is to simplify the construction of devices of this kind without interfering with the eflectiveness of the operation.

Anotherobject is to provide a means for producing a more powerful throw of the boomerang or other missile without materially increasing the size or'cost of the appliance.

Thedevice may be used as a toy, but is not limited to such use. It maybe made of sufficient size and provided with actuating springs o-fsufiicient strength to make it an effective weapon.

Otherobjects and advantages may hereinafter appear.

Referring to the accompanying drawings which illustrate embodiments of the invention which are at present deemed preferable,

Figure 1 is a side elevation of the appliance showing the hammer of the weapon up.

Figure 2 is a side elevation showing the hammer in the retracted position, the side of the casing being broken away to show the hammer-actuating springs.

Figure 3 is a rear view looking from left to right of Figure 1.

Figure 4 is a cross section of line 4-4 of Figure 1.

In Figures 1 and 2 a boomerang is shown mounted in the hammer in readiness to be thrown therefrom.

Referring in detail to the drawings the casing'7 is provided with a handle portion 8 and with side pieces 9 above said handle portion. Between said side pieces 9 is pivotally mounted a hammer 10 on a pivotpin 11, the ends of said pivot pin being supported by said side pieces.

As shown in Figure 2, the hammer-actuating means consist of a tension spring 12 which occupies an elongated chamber 13 one end of said chamber communicating with the space 9 between the side pieces 9. At its front end said spring 12 is desirably fastened to a pin 14 which. extends across said chamber 13, and

at its rear end said spring is fastened to a pin 15 which bridges a recess 15 in the hammer 10. Below-the hammer 10 the casing is provided with an additional chamber 16 wherein is mounted a compression spring 17,

said spring 17 militating against hammer 1O rearwardly ofits pivot 11 thus cooperating with the tension spring 12 to move the hammer from the retracted position shown in Figure 2 to the forward or operated position shown in Figure 1. At each side of the hammer is a recess 17 a to keep the upper end of spring 17 from binding where it is led through this recessed portion of the hammer.

The hammer member 10 is provided with a seat wherein, as shown in Figures 1 and 2, a boomerang 22 or other suitable missile may be loosely seated. 23 designates a thumb-hold,

or operating extension with which the hammer is provided in order that it may conveniently be retracted by the hand.

The side pieces 9 may be integral with the body portion of the casing, and the groove or space 9 between said side pieces may be formed by casting, orotherwiseQ The elongated chamber 13 may also be walled in at its upper side by a wall 13'' which is integral with the casing, or said element 13 may consist of any suitable closing strip attached over the chamber 13. Any other variations of structure, such as fall within the scope of the appended claim, likewise come within the spirit of the invention.

By using the plate 13 to cover a groove therebeneath I which extends longitudinally of the barrel of the simulated firearm, cost of manufacture is reduced, one advantage gained being more convenient access to the front 'end of chamber 13 for the purpose of attaching tension spring 12 to pin 14:.

In operation the boomerang or other missile 22 is seatedwithin the recess 20 provided in the hammer 10, as shown in Figure 1, while the hammer occupies the down or spring-retractedposition. The operator then places his thumb upon the hammer-extension 23 and thereby retracts the hammer against the op-' position of springs 12 and 17 to the position shown in Figure 2. 'Then by allowing his thumb to slide off from the hammer-extension 23 he releases thehammer whereupon the springs 12 and 17 bytheir combinedaction i I i 1,759,471

quickl'y force the hammer from the position shown in Figure 2 to the position shown in Figure 1. This sudden movement of the hammer causes the inertia of the boomerang to withdraw it from its seat in the hammer a and to propel it forwardly to the object toward'which'the weapon is directed.

I claim:

A boomerang thrower having a body portion which simulatesa fire-arm, 'and having a groove channelled out longitudinally of the barrel thereof, a plate secured oversaid groove to convert it into an elongated chain her, a trigger adapted to throw a missile stationed near one end of said chamber, and a tension spring insaid chamber to actuate said trigger. v V

In testimony whereof I here unto affix my signature.
